Poor interior heating
« on: December 10, 2009, 07:22:44 »
Hi All
Mrs wizards G reg Rangie seems to have the worst interior heating in the world.
When the engine is up to temp the air from the blowers are luke warm. Is this normal ?
I replaced the thermostat, but that made no difference.

Disconnect both the pipes to the heater (under the bonnet) ,connect a hose pipe to one of them with hose clip and wack the tap on,you could have a blocked heater matrix which could be restriting the water flow. I used to have an old fx4 taxi which went like it,when i done this ,the water came out like liquid clay!!! I had the hottiest taxi around after that!!!

Agreed, air lock or sludge in the matrix.  The hard dahs RRC should be filled via the heater matrix feed pipes to prevent air locks, they don't flush themselves out.

I flushed it through with rad flush and found one of the air vent pipes off the heater.
Its still not fantastic but its a lot better than what it was.

Try a new thermostate, 88 degree, it might only have a 82 degree one in

Witht he engine running and up to tempt, stand the car still for 10 minutes and run the engine without the heater blower, then switch the blower on and see how hot it gets.

Also, feel the heater in and out pipes (the rubber ones) they should both be hot, ifone is hot and the other lukewarm then water isn't circulating fast enough ie the matrix is blocked or there is an airlock.

WARNING!

The V8 doesn't like to run that hot, the optimum temperature is something like 80 degrees.
